X-radiograph(s) of "Calvary" 

Editor: This is an X-radiograph of Andrea Mantegna's "Calvary". It's quite abstract in this form. What strikes me is the layered texture; what can we deduce about the underlying structure? Curator: The striations evident in the radiograph denote the support. Note how the varying densities suggest a panel constructed from multiple planks, joined horizontally. Editor: So, the image itself reveals the material history, the construction process? Curator: Precisely. The X-ray unveils the very physicality, the substratum upon which Mantegna’s vision was realized. A fascinating interplay of art and material science, don't you agree? Editor: Absolutely, it allows us to appreciate the process in a new light. It brings a unique perspective to the original painting.
